alright guys i gotta know what you think i should do. i have 2 kicker 10" comps in my mustang right now and i think its time for an upgrade. i want to get either 2 12"s or 15"s but idk if i can fit 15s in the mustang cause the mach 460 takes up so much **** space. what subs would you guys recomend for a $300-400 budget. and would you go with 12's or a single 15 or 2 if they can fit.
